How can I improve the accuracy of my sample size in research?

To improve accuracy, consider increasing your sample size, ensuring random selection, and minimizing bias.

What factors should I consider when determining my sample size?

Key factors include the population size, desired confidence level, margin of error, and variability in the data.

Is there a formula I can use to calculate the sample size?

Yes, you can use the formula: n = (Z^2 * p * (1-p)) / E^2, where Z is the Z-score, p is the estimated proportion, and E is the margin of error.

What is the impact of a larger sample size on my results?

A larger sample size generally leads to more reliable results, reduces the margin of error, and increases the power of your study.
